摘　　要：红树林中有丰富的固氮微生物，尽管它们是红树林生态系统的氮素生物地球化学循环中不可缺少的成分，但相对于其它成分，固氮微生物的研究较为薄弱。近年来的研究表明，这些固氮微生物与红树植物生活在一起，可以相互从对方获得生长所需的营养物，同时这些微生物又不可避免地与其他微生物产生相互作用。受环境因子的影响，固氮微生物的固氮活性在不同季节和不同演替阶段的红树林中有较大的差异。本文综述了近年来红树林固氮微生物的研究进展，相对于其他系统的固氮微生物的研究，红树林固氮微生物的研究还有待于加强。There are abundant nitrogen-fixing microorganisms in the mangrove forest. The reports on nitrogen-fixing microorganisms in mangrove forest are scarce though they are the indispensable components in the geochemical sycle of the nitrogen organisms in the mangrove forest and their role could not be ignored at any rate. However, in recent years, some researches shows that nitrogen-fixing microorganisms and mangrove plants are able to obtain nutrient matters from each other because both of them exist simultaneously in the mangrove ecosystem. At the same time, other microorganisms influence nitrogen-fixing microorganisms strongly. The nitrogen-fixing activity from these microorganisms is different in different seasons and different succession stages of mangroves owing to the effect of environmental factors. The advances in the reseach on nitrogen-fixing microorganisms in recent years are reviewed in this paper. The further studies on nitrogen-fixing microorganisms should be carried out in various ways in the mangrove forest compared with other ecosystems.
